[Resolved] Wrong address of primary blog?

I just uninstalled an old version of a blog and installed WordPress according to instructions for multisite, choosing subdomains for extra blogs. I installed in a subdirectory, according to instructions for WP 3.5 & up, with the blog address in the root directory.

I should mention that this is the second time I’ve tried this, having deleted the previous installation because I thought something must be wrong and a clean install would be easier than trying to figure out what was wrong. (So much for that thought!!)
